C++ :: Console Applications Keep Crashing
Jan 11, 2013
Any time I run my program after I make a selection from the menu the output is printed on the console screen then immediately a windows screen comes up saying project.exe has stopped working.
Below is my code, and I suspect the error has something to either
A) due with how I'm calling the method or
B) how I have the method coded.
Main
#include <iostream>
#include <fstream>
#include <string>
#include "telephone.h"
#include "tbook.h"
[Code] .....

I'm working a personal project where I have two applications namely Server, Client. when Server is started, it continuously transmits data. When Client is opened, it is ready to consume the data and display it.
I will put both .exe files in a shared location (LAN). Therefore Sever and Client will be launched from different machines. When I searched for articles that teach how to establish communication between the two, I was offered with choices like NamedPipes, WCF, Polling etc.. I'm not sure whether they will work in a LAN based environment.Also are there any other means of establishing communication?

I need to write a windows form application that allows the user to enter a credit card number and credit card type and then determines whether it is a valid number using the following rules:
1.) the first number is:
a. 4 for visa
b. 5 for master card
c. 37 for american express
d. 6 for discover
2.) passes the mod 10/ luhn check, which is calculated as:
a. from right to left, multiply every other digit by 2. when doubling a digit results in a two digit number, add the numbers to get
a single digit. ( like 6 * 2 = 12 therefore 1 + 2 = 3).
b. add all the single digits from 2a
c. add all the odd places from right to left in the card number
d. sum the results fro steps 2b and 2c
e. if the resulting number in 2c is divisible by 10, the card number is valid otherwise it is invalid.
The chapter is introducing methods so that is the main thing i will be using for each step.

I want to create an application that automatize different applications in the sense that my application will be able to press automatically different buttons on another application.
For example: my application will start, let's say, Microsoft Office, will press some buttons in MSOffice, and will close MSOffice.

I'm looking for a library which enables me to take screenshots of a all open applications, and store them as .bmp or .jpg .
I've tried to find something but so far no luck
I don't necessarily need code just a library with good understandable documentation (if such a thing exists). Also, is something like this possible for a beginner-intermediate c++ user? If not where should I start?

I have a service that has some settings. As the service is running as a system user, the settings file is located in
C:Windowssystem32configsystemprofileAppDataLocal<PRODUCTNAME><ExecutableName+GUID><VERSION>user.config
Now i want to be able to change some settings at runtime using a normal Winforms App. Is there a good and easy way to change the user.config of a different application directly? I tried with ConfigurationManager but that does not seem to work.

I'm trying figure out how Windows Firewall functions by experimenting with Bittorrent's add exception to windows firewall option, I deleted the entry from the Firewall options and also located that the regkeys are in HKLM/System/CurrentControlSet/Services/SharedAccess/Parameters/FirewwallPolicy but I can't figure out what registries are made when an application is added as an exception in the Windows Registry.

I intend writing a Windows form c# application that freezes windows and disables all other running application in the background while executing for security reasons. How I could go about this?

I will sketch the scenario I would like to get working below. I have one main application.
That application, based on user interactions, can load other applications in a secure shell. This means these child applications cannot interact with the OS anymore, nor with each other.
The parent program can at any time call functions of these child programs.
The child program can at any time call functions of these parent programs.
How to implement this in C++? Preferably both parent and child should be written in C++.
The performance of loading the child applications doesn't matter. The only thing that matters is the performance of the communication between child and parent.

My program is crashing when I'm trying to call b = a. What has me confused is that when I call c = d = b, it all works fine.
I actually think I see it now that I posted this. In operator= I'm changing the size, but I'm not changing the size of the array that it's pointing to correct? I'm keeping it as 'p = new T[size]' rather than changing it to 'p = new T[x.size]' correct?
#include <iostream>
#include "Array.h
int main() {
std::cout << "creating Array< int > object a ...

My app keeps crashing after about the 49th insert.
I tried debugging and it keeps pointing to this area in the Fixup:
if (z->parent == z->parent->parent->left) {

i am trying to break a string and store it to a stiva (tail) i need my program to take one function like this
(a+10)* ((b+c)/(d-5)) + (9*2)
and return if it is editorial correct for example for the apper function has to return true but for this function
((a+10)*((b+c)/(d-5)) + (9*2)
has to return false.it crashes in the last part of my list i will put a comment
Code: #include<iostream>
#include<stdio.h>
#include<conio.h>
#include<stdlib.h>

Code:
#include<stdio.h>
//bookData structure
struct bookData {
int recordNum;
char description[ 15 ];
int booksBought;
double bookCost;
[code]...
I am able to add records and show records, no problem. But when I go to delete a record, it crashes immediately after inputting the record number I want to delete. I don't see why. I've set it up exactly like the example in my book, having of course changed the variable names for my program. Does it have something to do with the pointer?

When I go to run the Fibonacci function ( fib ), it begins to return incorrect calculations towards the higher numbers, but then seems to correct itself for a little bit, but then does it again and ultimately crashes. And the program seems to be crashing at random numbers. Sometimes the it will make it up to F(55), other times it will only get to F(20).
Also, when I go to run the program on a Linux server, it segfaults, but it doesn't when I just run it on my IDE. the function adds two arrays with individual digits together. It does this to allow the program to add numbers that would exceed the boundaries of INT_MAX.
Here is the header file "Fibonacci.h":
Code:
#ifndef __FIBONACCI_H
#define __FIBONACCI_H
typedef struct HugeInteger
{
// a dynamically allocated array to hold the digits of a huge integer
int *digits;
// the number of digits in the huge integer (approx. equal to array length)
int length;
} HugeInteger;
}

I was writing a program and it started crashing on exit (segment fault), after the 'return 0' in main(). I figure it's an std destructor.
I started with the program I was writing and just stripped out as much as I could, while making sure the crash persisted. If I remove any of the remaining code the crash disappears, even the seemly unrelated or scoped code.
#include <iostream>
#include <fstream>
#include <condition_variable>
#include <mutex>
#include <thread>
/* Call stack results:

I know everything works except my copy constructor! There are no errors. The program crashes when it goes to access the copy constructor. why the copy constructor isn't working?
#ifdef _MSC_VER
#define _CRT_SECURE_NO_WARNINGS
#endif
#include <cstring> // access to C str functions
#include "String.h" // access String class
using namespace std;
String::String( int size )// default constructor

This program I'm working on accepts an array size from the user, prompts the user to store that many integers, sorts them from smallest to largest, and then searches for duplicates with a simple for loop. The ultimate goal of the assignment was to display duplicates in an array, and the rest of the functions are just how I decided to reach that goal.
Anyway, my program crashes if I choose an array size larger than 7. It sorts and displays duplicates perfectly with 7 or fewer arguments.
The exact moment it crashes is after I enter the final value it prompts me for, so it appears my inputsize() function and my inputarray() function are working, and the error may be in the arrsort() function. Code is below:
Code:
#include <stdio.h>
int funcinputsize(int);
void funcinputarray(int [], int size);
void funcarrsort(int [], int size);
void funcdupe(int [], int size);

The first problem i'm having is in the following code.
Code: #include<stdio.h>
#include<stdlib.h>
#include<time.h>
// program ask for max value and always returns random numbers < max
[Code].....
The ultimate goal of these two programs is to merge them and make one program that takes a max value from the user and fills up an array of (10^6) elements with values ranging from (0 to maxValue).

I've been making a multilayer game for a while and have a config that the game loads for the IP and stuff. I just recently put all the loading stuff into a function just so its easier to go through the code, but now the game isn't really working. It works fine on my computer connecting to the server myself, but when someone else tries to do it it seems like the game is working like it says the IP and everything from the config. When it tries to connect it either doesn't work or crashes just saying the program stopped working. Here is the code... I don't know if this is what is causing it to not work or something else.
string LoadConfig(int &loadPort, bool &fullscreen) {
string file;
string loadIP;
vector<string> fileLines;
fstream config("config.txt");
if (config.good()) {
